Title: Railway track section safety monitoring circuit - uses track coils interfaced to relay via transformer with saturation characteristic
Inventor: DICKSCHEN ARNO
IPC: B61L1/18
Filed: 1977-11-30
Abstract: A safety circuit (1) is used for monitoring sections of railway track using track circuits. It has a track choke designed according to the track monitoring voltage frequency. The choke primary windings are connected between the tracks. The track monitoring voltage is fed via secondary windings to an alternating current relay energised if the section is free. It prevents faulty indication of a free section arising from transient drive current variations with asymmetric choke loading. The relay is connected to the choke secondary winding via a special transformer with a linear characteristic up to a given voltage above which it saturates.

Patent DE-2816558-A1 (DE)
Inventor: BRUNGSBERG HEINRICH
IPC: H01H47/22
Filed: 1978-04-17
Abstract: In the case of driving a bistable relay which switches an AC circuit, the relay coil (3) is energised by briefly closing a switching element (1). In order to open the relay contact (4) deliberately 20 DEG  to 10 DEG  electrically before the zero crossing of the AC voltage, and to achieve deliberate closing of the relay contact (4) up to 20 DEG  electrically after the zero crossing of the AC voltage, a bias resistor (2) is arranged in a series circuit with the relay coil (3) and the switching element (1). For this purpose, the pull-in current of the relay coil (3) can be matched to the movement sequence of the bistable relay (3). This bias resistor (2) is expediently split into a resistor (2a) and a PTC thermistor (2b). <IMAGE>
Patent DE-2817898-A1 (DE)
Title: NC machine tool with multiple tooling system - has necessary data stored to select null point for each tooling system
Inventor: SCHUERFELD HORST ING GRAD
IPC: G05B19/408
Filed: 1978-04-24
Abstract: The N C machine tool has a sensor reference point (R) which is defined by ordinates (L1, Q1) w.r.t. the tool system null point (I). The computer then determines the required position of the tool at the point (P) with ordinates (L) and (Q). With different tooling systems the null point changes, which involves a resetting of the input data to the computer. This task is eliminated by storing the necessary information for each tooling system in the computer so that when the tooling system is changed, the computer automatically selects the correct null point.

Title: Material separation by ionisation - after atomisation through radiation with absorption spectrum line frequencies
Inventor: STEPIN BORIS DMITRIEVITSCH
IPC: B01D59/50
Filed: 1978-05-16
Abstract: Sepn. process is based on the complete atomisation of the material and on the ionisation of the atom species to be sepd. through electromagnetic radiation. The frequency of this radiation is closed to suit that of the absorption spectrum lines of the atom concerned (1000-15000 angstroms). Used in mfr. of materials for nuclear and semiconductor technology, fibre optics and optical glass prodn., including reflective coatings. This facilitates an exact quality and compsn. control of the sepd. prods. and the automatic supervision of purificn. processes. High-purity single and multi-layer films of given thickness can be produced automatically. Typically, the process is used to separate rubidium and potassium from a mixt. of their chlorides.

Title: Air pressure regulator for compressor output - with single control piston and vented control actuator which lifts off at specified pressure
Inventor: SIEBOLD MANFRED
IPC: G05D16/16
Filed: 1978-07-21
Abstract: A pressure regulator of the type used to control compressor output, uses a single control piston with a vented actuator. Air from the compressor (2) is passed to outlet (5) over a check valve (14). When output pressure is too high a control pressure is applied to an actuator (22) that lifts off its seat against spring pressure (42). Pressure is applied (13, 26) to the main valve piston (28) that vents to atmosphere (29, 30). When pressure falls below the set level, the control actuator seals against output pressure and a vent path is opened (21) to allow the main piston (28) to close.

Title: Decatising machine drum-liner - is formed from a cut length of synthetic needle-felt with chamfered ends
IPC: D06B7/08
Filed: 1978-07-29
Abstract: A drum-liner for a decatising machines is composed of several layers of a synthetic-fibre needle-felt, formed from a cut length of the felt with chamfered ends. The felt is wound on to the drum in the normal direction of rotation of the drum, and the chamfered end is smoothed into the underlying layer to make a seamless join. The felt may consist of several superposed webs laid with fibre directions at right angles to each other, and which may enclose a stabilising sheet of woven or knitted fabric. The fibres are pref. of aromatic polymide material which is resistant to hydrolysis and to high temps. The felt provides a uniform structureless, porous surface which does not mark the surface of the fabric being treated. The covering of a drum can be replaced in a matter of minutes, as opposed to the two days required to replace the traditional sleeves of woollen felt, resulting in higher machine productivity.

Title: Pneumatic tyre for motor vehicles - with thermally less stable treat elements indicating over-stress visibly and audibly
Inventor: HUININK HEINRICH DIPL ING
IPC: B60C11/00

Title: Traveller-mounting pliers for ring-spinning frame - having removable face-plate for extraction of damaged travellers
Inventor: NIMKE BURKHARD
IPC: D01H17/02
Filed: 1979-07-07
Abstract: A plier-like tool for mounting travellers on spinning rings has a spring-loaded face-plate attached to the setting jaw which can be moved away from its working position against the side of the jaw to allow access to the inner side of the traveller magazine. The face-plate is part of a separate assembly which includes a setting device for adjusting the clearance between face-plate and jaw to suit different sizes of traveller. The assembly is slidably mounted in bushes attached to the jaw, such that it can be unlocked and slid out of its working position without affecting the clearance setting. Construction allows blockages to be rapidly cleared without partial dismantling of the pliers, and without danger of damage to the mechanism. The tool is then immediately ready for re-use, without tedious re-setting procedures.

Title: Holder for storing electronic components prior to processing - has tubular magazines held in holes in stack of horizontal support grids
Inventor: DUELL HELMUT
IPC: H05K13/04
Filed: 1979-08-30
Abstract: The holder consists of several plane-parallel grids (5). The bottom grid is closed by a cover plate (9). The grids are horizontal and held apart by vertical spacers (23). The heights of the spacers decrease in passing up the stack. The cross-section of the holes (7) in the grids becomes gradually smaller in passing down the stack so that the cross-section of the holes in the bottom grid is roughly equal to the size of the components being stored. The holes in each grid are conical, tapering towards the bottom. Tubular magazines (1) fit into the holes and hold electronic components prior to inserting into circuit boards during the fabrication of the latter.
